Meteorologists are warning that an incoming subzero cold snap comes with an increased risk of "exploding trees." Arborists say it's a real thing that

Forecasters warn an extreme winter storm could trigger rare “exploding trees” across the Upper Midwest as temperatures plunge below zero, causing sap inside trees to freeze and crack bark. The storm is expected to bring widespread snow,

Tree sap is mostly water with sugars and minerals, and like many liquids, it expands when it freezes. Gradual freezes usually don’t harm trees — even if it gradually cools to subzero — but plunging temperature swings cause uneven freezing and internal pressure. This stress can crack the bark and wood, producing what sounds like a loud pop.

The internet is buzzing with talk of “exploding trees.” While it makes for a snappy headline, meteorologist Brendan Johnson explains why it’s just more misleading clickbait.
